Season and Color


Herbaceous peonies bloom at varying times throughout late spring and early summer. The earliest begin blooming in mid-May. The bloom is usually finished by the Summer Solstice, however on a particularly cool year blooms may continue into early July.

Distribution of bloom time within the Nichols Arboretum Peony Garden


Traditionally, herbaceous peonies come in four colors: white, blush, pink, and red. Through modern breeding, a greater range of colors has been achieved including coral, yellow, and patterned peonies. However, due to the historical nature of the peony garden, the peonies in this collection are within the narrower, traditional color range.
